Legal age to buy zippo fluid?

Question

I wanted to know the legal age to buy zippo fluid because i have a zippo and it ran out of fluid.

Answer 1

If you're going to buy it at a store, the legal age may be the same as for spray paint, which in Texas is 18.

Answer 2

I think it has no age limit seeing as that you can buy it in amazon.com and you don't need to be any age to register a amazon account.
